In the fictional Stolen Valor Act case of US v. Fields, what was the argument of the prosecution from Field's lies?

The agrument was Protected by free-speech. The law made it a government crime to erroneously speak to oneself as having gotten any U. S. military beautification or decoration. In the event that sentenced, respondents may have been detained for up to a half year, unless the adornment lied about is the Medal of Honor, in which case detainment could have been dependent upon one year.
